What is the best way to show html-formatted text in a flex mobile
app?
I just want to display a text with some bold or colored words in an
itemRenderer. What is the best way (performance, ...) to achive this?
Best regards
Christian

I have used it in mobile apps. I haven't seen real performance problems.

Thanks for the great responses... But one question left...
Aren't there problems with performance when using a RichText in a Mobile Air
App? I remember Adobe warned to use it in Mobile Apps. Has something changed
...
Thanks

I responded to a similar question a while ago. Something similar to what
Jude has explained above:

Thanks,

You might be able to reuse the LabelItemRenderer renderer and substitute in
the old text field and set it's htmlText property rather than the text
property. That might be the fastest but a lot more work if it uses Spark or
FTE API methods.
You could create an item renderer with the old text field and set it's
htmlText property. Something like,
<s:ItemRenderer xmlns:fx="http://ns.adobe.com/mxml/2009"
xmlns:s="library://ns.adobe.com/flex/spark"
xmlns:mx="library://ns.adobe.com/flex/mx"
creationComplete="addComponents()">
<fx:Script>
<![CDATA[
public var textField:TextField;
public function addComponents():void {
textField = new TextField();
addElement(textField);
}
override public function set data(value:Object):void {
textField.htmlText = String(value);
}
]]>
</fx:Script>
</s:ItemRenderer>
The above is pseudo code so it will need to be tweaked.
You could also use a RichText and use a TextFlow or use the HTML
importer class.
<?xml version="1.0" encoding="utf-8"?>
<s:ItemRenderer xmlns:fx="http://ns.adobe.com/mxml/2009"
xmlns:s="library://ns.adobe.com/flex/spark"
xmlns:mx="library://ns.adobe.com/flex/mx">
<fx:Script>
<![CDATA[
override public function set data(value:Object):void {
//super.label = value;
if (value is TextFlow) {
labelDisplay.textFlow = value as TextFlow; }
else if (value is String) { // import HTML markup
labelDisplay.textFlow = HTMLImporter.importToFlow(value); }
]]>
</fx:Script>
<s:states>
<s:State name="normal"/>
<s:State name="hovered"/>
<s:State name="selected"/>
</s:states>
<s:Rect left="0" right="0" top="0" bottom="0">
<s:stroke.selected>
<s:SolidColorStroke
color="0x000000"
weight="1"/>
</s:stroke.selected>
<s:fill>
<s:SolidColor
color.normal="0xFFFFFF"
color.hovered="0xCEDBEF"
color.selected="0x00FF00"/>
</s:fill>
</s:Rect>
<s:RichText id="labelDisplay"
fontWeight.selected="bold"
verticalCenter="0"
left="3" right="3"
top="6" bottom="4"/>
</s:ItemRenderer>
The code above is also pseudo code.

Check for textflow
